In the heavenly school. . . every redeemed one will understand the ministry of angels in his own life. The angel who was his guardian from his earliest moment; the angel who watched his steps, and covered his head in the day of peril; the angel who was with him in the valley of the shadow of death, who marked his resting place, who was the first to greet him in the resurrection morning--what will it be to hold converse with him, and to learn the history of divine interposition in the individual life, of heavenly co-operation in every work for humanity. --Education, Page 305.
